Explanation:
The force that keeps everything on Earth's surface is the gravitational force. Earth has a large mass, and any object near its surface experiences a force of attraction towards the center of the planet. This force is what prevents people from falling off Earth's surface. Even though we may not feel it, we are constantly being pulled towards the center of the Earth. This force is what gives us weight and keeps us grounded.
People on the opposite side of the globe do not feel upside down or sideways because the gravitational force is acting perpendicular to the surface of the Earth. So, regardless of our orientation, we always feel as if we are standing upright on the ground. This is why we do not feel any different if we were to travel to the other side of the world.
Objects fall down because of gravity. When an object is released from a height above the ground, it falls towards the center of the Earth. This is because the force of gravity is pulling the object towards the Earth's surface. As the object falls, its speed increases, and it accelerates towards the ground until it reaches terminal velocity. This is the maximum speed at which the object can fall due to the resistance of the air. The force of gravity is what causes objects to fall, and it is the same force that keeps us on the surface of the Earth.
